o 91mm 9 1M8 WIRE CLOTH OR FABRIC Application filed February 13, 1931.Serial No. 515,490. 7

This invention relates to woven wire cloth or fabric, such as is used onpapermaking machines, and the principal object of our invention is toprovide a joining of the ends of the cloth or fabric in such a manner asto obtain a maximum ofstrength and a minimum drainage obstruction, whichis essential-for the successful operation under the exactingrequirements to which a wire cloth or fabric of this nature is subjectedA further object is to-make a joining of the ends of the cloth orfabricin such a manner as to obtain a uniform impervious cloth or fabric atthe point of joining.

A further object is to make a joining of the ends of the cloth or fabricinsuch a manner that such joining or uniting is intermediate the top andbottom surface planes of the fabric. i v

1 A further object is to make a joining of the ends of the cloth orfabric by uniting the protruding ends of the Warp wires of one end ofthe cloth or fabric, intermediate the marginal weft wires of therespective joined portions, to'the opposite end of such wire cloth orfabric.

lVith the foregoing and other objects in view as will appear as thedescription procoeds, the invention consists of the novel construction,combination and arrangement of co-operating elements as hereinafter morespecifically set forth, claimed and shown in the accompanying drawingforming a part of the present application, in which:

Fig. 1 and Fig. 2 are longitudinal section views of the respective endsof the wire cloth or fabric which are to be joined, and

Fig. 3 is a longitudinal section view of the respective ends of the wirecloth or fabric showing them as joined.

Like numerals of reference designate corresponding parts throughout thedifferent views.

Referring to Fig. 1, this end of the wire cloth or fabric ischaracterized by the fact that the warp wires and 6 are securely united,in their woven position, to the marginal weft wire 4;, by soldering,welding, fusing, brazing, or other like manner. After the wires 4, 5 and6 are united, the protruding ends of the wires 5 and 6 are cutofi' as ona line AA of Fig. 1, which line of cutting is substantially flush withthe outer edge of the marginal wire 4. I I I 1 Referring to Fig. 2, thisend. of the wire .55

cloth or fabric is characterized by, the fact that the warp wires 5and,6;,,a re securely united, in their woven positiomgto the weft wire7, which is the next to the marginal weft wire 8, by soldering,welding,.fus ing,h brazing, or other like manner. After the wires '7, 5"and 6 are united, the protruding ends of the wires 5"a11d 6 are cut offas on aline B-B of Fig. 2, which line of. cutting is substantially flushwith the inner edge of the .65 marginal wire 8. Thus, the weft wire 7becomes the marginal'weft wire of, this poIition of, fabric. 1

Referring to-Fig. 3,.we have I hown th'e free ends of the warp wires5and 65. as abutting the ends of the warp wiresfi and, 6 respectively, onthe line CC. 'Whi leheld in such abutted position, these ends arese-'curely united to provide an integral. connection between the respectivewarp wires 5 5 and the weft wire 1 and between the respective warp wires66 and the weft wire .4, by soldering, Weldin g, fusingor brazing orother like manner; This providesa continuity of the wires 55 and 66inuniform woven relationship, with a minimum drainage obstructionintermediate the weft or warp wires at the point of joining. We do notwish to be limited to the warp wires 5. and 6 having to precisely abuttheir respective warp wires 5 and 6.. The protruding ends ofthe warpwires 5 and 6 may abut and contact with the marginal weft wire 4'intermediatetheiwarp Wires 5 and 6 either vertically or laterally.

By cutting the portionof fabric. as shown in Fig. 1, on the line AA,Where thewarp wires 5 and 6 are in converging relation to each other,and, by: cutting the ,portion ,of fabric as shown in Fig. 2, on the line13 B, where: the warp wires 5 and 6 are in diverging relationship toeach; other, the 1 warp wires 5, 6, 5 and 6 are cut on an an 1e andconsequentlythe abutting faces of vsuc 7 warp wires provide a; greaterarea, than the normal cross-section area thereof. Furthermore, the

contacting faces thereof are preferably cut in parallel planes and theends of the warp wires to be joined are intermediate and in spacedrelation from the top and bottom surface planes of the respectiveportions of fabric, when the warp wires 5"and 5iv and .6 and 6' are"joined respectively. "By joining the respective warp wires, as on theline C- C-of Fig fi and in .themanner .as hereinhefore described, the'respective contacting warp Wires are in direct longitudinal alignmentwith each other and form an uninterrupted uniform mesh formation at thepoint of joining.

The foregoing specification and annexed "drawing disclose the preferredembodiment .iof our inventionghutit is 'to be understood that minorchan-ges may be'resor-ted to in the commercial, adaptation of ourinvention without departing from the scope 'of'the invention ashereinafter claimed.

What we'claim as new is:
